Road Centerline 2025

Overview This feature service provides a detailed dataset of road centerlines representing all roadways and carriageways within the Cape Cod region. The data supports critical regional transportation planning, address geocoding, and infrastructure management. Feature Layers RoadCenterline: This layer contains comprehensive road segment information derived from high-resolution aerial imagery acquired in Spring 2025. The imagery has a ground sample distance of 7.5 cm and meets rigorous positional accuracy standards, ensuring reliable spatial representation of streets and roadways. Geographic Coverage The dataset covers the Cape Cod region with precise spatial extent aligning to local governmental boundaries. The geographic scope supports a variety of public planning and operational activities within this southeastern Massachusetts area. Use Cases Supporting emergency response by providing accurate road network data Address geocoding and location-based services Transportation infrastructure planning and maintenance management Integration with public works and municipal operational systems Data Source and Quality The data was collected by NV5, funded by the Cape Cod Commission, using leaf-off, snow-free aerial photography captured between February and April 2025. This project focused on updating existing planimetric datasets with added features and ensuring high positional accuracy suitable for detailed spatial analysis.【概述】本要素服务（feature service）提供一套覆盖科德角（Cape Cod）区域内所有道路与行车道的详细道路中心线数据集。该数据可支撑关键的区域交通规划、地址地理编码（geocoding）以及基础设施管理工作。 【要素图层】道路中心线（RoadCenterline）：该图层包含由2025年春季获取的高分辨率航空影像提取所得的完整道路路段信息。此次航空影像的地面采样距离（ground sample distance）为7.5厘米，符合严格的位置精度规范，可确保街道与道路的空间表达准确可靠。 【地理覆盖范围】本数据集的空间范围精准匹配马萨诸塞州东南部科德角区域的地方政府管辖边界，可支撑该区域内各类公共规划与运维活动。 【应用场景】1. 提供精准的道路网络数据，支撑应急响应工作；2. 支持地址地理编码与基于位置的服务；3. 服务于交通基础设施规划与养护管理；4. 可与公共工程及市政运维系统集成。 【数据来源与质量】本数据由NV5公司采集，由科德角委员会（Cape Cod Commission）资助，采用2025年2月至4月期间获取的无叶、无雪航空摄影数据。本项目旨在更新现有平面数据集，新增相关要素，并确保具备适用于精细空间分析的高位置精度。
